Episode notes
From Bitcoin Magazine X Spaces, Business Reporter Juan Galt sits down with Roy Sheinfeld, co-founder of Breeze, to discuss the evolving architecture of Bitcoin's Lightning Network and how Breeze is working to make Bitcoin more usable as a medium of exchange. Roy explains Breeze’s unique SDK architecture, the role of Lightning Service Providers (LSPs), and the technical trade-offs of custodial vs. non-custodial systems.
The conversation dives deep into the mechanics of self-custody, key management, watchtowers, and the controversial use of stablecoins like USDT on Lightning via Taproot Assets. Roy also shares what’s coming next for Breeze—including support for Bolt 12, BIP 353, Nostr Wallet Connect, and WASM.
